Will a 1989 4 liter jeep engine interchange with 2004 engine?
The 1989 4-liter Jeep engine and the 2004 engine are not interchangeable. The 1989 engine is a straight-6 engine, while the 2004 engine is a V6 engine. The two engines have different bolt patterns, different fuel injection systems, and different electrical systems. Additionally, the 2004 engine has a larger displacement and produces more power than the 1989 engine. As a result, it would be very difficult to swap the 1989 engine for the 2004 engine.
